A differential gear apparatus includes a housing for rotation about a predetermined axis under the power of an external power source, and a lubricating oil reservoir and worm gear arrangement mounted in the housing for rotation. A lubricating arrangement is disposed with respect to the housing for guiding the lubricating oil from the lubricating oil reservoir to the work gears against centrifugal force created by rotation of the housing.

Differential gear apparatus with worm gears

A bias ratio levelling apparatus for a worm gear type differential include first and second shafts mounted on a common axis first and second worm gears fixedly provided in the rotational direction at opposed end portions of the two shafts, a first worm wheel directly intersected with the shafts and engaged with the first worm gear, a second worm wheel directly intersected with the shafts and engaged with the second worm gear, a rotatable member for rotatably bearing the first and second worm wheel about a central axis and for rotating first and second worm wheel about the first and second shafts. A spur gear is fixedly connected to each worm wheel for transmitting the rotation of one worm wheel to the other worm wheel by synchronization, and a spacer is interposed between the first and second worm gears and axially fixed to the rotational member in the direction of the first and second shafts.
